COMPRESSED-AIR SPRAYER.

SPIEGIFICATION formingpart of 1 Letters Patent No. 676,204, dated June 11, 1901.

Application filed September 4j 1900- Serial N- (N0 model-l To all whom,it may concern):

Be it known that I, FRANK RIPP'LEY, of the city of Grafton, Jerseycounty, State of Illinois, have invented certain new and usefulImprovements in Compressed-Air Sprayers, of which the'following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

This invention relates to compressed-air view illustrating the operationof one form of the sprayer. Fig. 2 is a side elevation of the same. Fig.3 is a sectional elevation taken on the line act of Fig. 4. Fig. 4 is atop plan View. Fig. 5 is a sectional plan view taken on the line b b ofFig. 2.

1 indicates a tank for holding the liquid and containing the air underpressure. Said tank is provided at its top with a suitablefillingopening 2, provided with any common form of air-tight closure 3.Upon one side of said tank is fixed a concaved shield 4, which extendsparallel with said tank, almost the full length of the latter, and isconnected therewith by means of suitable braces 5, whereby the body ofthe wearer may fit within said concavity during use of the device andhold the latter more securely in position. Further means of supportingthe device on the body of the wearer is shown in Fig. 1. I provide theshoulder-strap 6, which is adapted to be extended over one shoulder andthereby support the device in position. The ends of said shoulder-strap6 may be connected by means of snap-hooks or other common fasteningswith suitable loops or rings '7, secured to opposite sides of said tank.

8 indicates the barrel of a common airpump, loosely mounted to slide ina cylindrical shield 9, fixed at an angle to oneside of said tank 1 bymeans of suitable brackets or braces 10, and said pump-barrel isdetachably threaded into a socket 11, fixed upon the side of said tank.

12 indicates an air-pipe for. conveying air from said pump into saidtank, and said pipe extends from said socket in through the wall of saidtank and upwardly therein to a point adjacent the top of the tank 1, asshown by dotted lines in Fig. 2.

13 indicates a hose through which the liquid is discharged from thetank, and said hose is connected, preferably, to the tank at a pointnear the bottom thereof and is pro vided with a common valve orstop-cock 14., the outer end of which may be provided with any commonnozzle 15.

16 indicates an eduction air-pipe, which extends upwardly within saidtank 1. to a point adjacent the top thereof, (see Fig. 3,) and thencepasses through the wall of said tank adjacent the lower end thereof andconnects with the liquid-discharge pipe 13 and is pro vided with a valveor faucet 17 at a point exterior of the said tank for a purposehereinafter mentioned.

The operation is as follows: The tank 1 is to be filled about two-thirdsfull with any approved solution, or it may be whitewash, if the deviceis to be used for spraying paint or whitewash. Then the tank is to becharged with compressed air by operating the air-pump until a suitableamount of air is compressed above the liquid therein contained. Thepressure can be readily determined by the increased amount of forcerequired to work the pump. When it is desired to use the device as acommon sprayer, the stop-cock 1 1 is opened, so that the liquid isexpelled through the hose 18 and nozzle 15, as shown in Fig. 1.

I claim- In a compressed-air sprayer, a main tank, a cylindrical shield9 attached to one side of said main tank and being at an incline, athreaded socket 11 in alinement with said shield, an air pump mountedwithin said shield, and having its lower end threaded into the socket,an air-pipe 12 leading from said socket into the main tank and extendingupwardly to near the top thereof, an outletpipe 13 leading from near thebottom of the main tank, a stop-cock for controlling said outlet, aneduction air-pipe 16 Within the In testimony whereof I aflix mysignature main tank and. leading from near the top to in presence of twowitnesses. the bottom and bemg extended through the FRANK RIPPLEY.

wall and being connected to the outlet 13, and

a Valve 17 for controlling the passage of the Witnesses:

air through said pipe 16, substantially as WILLIAM vBROWER, specified.MASON CALLAWAY.
